Application filed June 23, 1924. Seria1 No. 721,801.

To (all iii/mm h registering apertures forming a passage- Be it known way 15 located in the bottom of the cup 6. Also they are apertured in a similar manner to provide a passage 16 outside the cup 6 and which may be fitted with the collared bushing1'7, the protruding end of which is adapted to receive one end of a flexible tube delivery 20. i I

To the back board 3 of the bellows 1 is securely fastened the vertically disposed bar 25, to the upper end of which is pinned one end of the curved. handle 26 provided with any suitable gripping means 27. The other end 28 of the handle 26 is bent around so as to form the handle 26 in the shape of a letter J seen in Fig. 1. At the extremity of the end 28, the handle 26 is pinned to the end'oi a substantially horizontally di posed connecting bar 80, the other end 31 of which is pinnedto a bar 32 rigidly secured to the front board a of the bellows 1 and extending in the same plane therewith. The free end of the bar 32 is bent angularly to form the extension 33 which is apertured at its end. to receive the hooked en l 3 1 of a spring 35. The other end of this spring 35 is hooked into the extremity 2-36 of the base 7 of the casting 5; The parts are so constructed that the spring with its supporting bar 32, connecting link 80, handle 26, and bar 25, are substantially in the same vertically disposed plane, will be'clear from Figs. 1 and 3. The bar 32 is suitably apertured above the bellows 1 to receive a link 40 provided at its other end with a hook 41' adapted to engage the eye 42 formed in. the end o1": the horizontally disposed extension l3oi' the vertically disposed stirring rod or agitator.

An apertured guide plate 417 is pos may concern.- that 1, JOHN A. Rnonns, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have inventedcertain new and useful Improvements in Powder Sprayers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an apparatus for spraying plants with powder or the like, andhas for its object to provide a simple mechanism of this character which will be more efficient in use endless costly to 1nanufacture than those heretofore proposed.

With these and other objects in view, the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

v Referring to the accompanying drawings, forming a part of this specification, in which like numerals designate like partsin all the views Figure 1 is a perspective side view of the device made in accordance with this invention;

Figure 2 is a fragmentary view of the device partly in section showing details of construction Figure 3 is a view taken on the line 33 of Fig. 1, looking in the direction of the arrows; and

Figure 4: is a diagrammatic view illustrating the use of the device.

1 represents a bellows comprising the collapsible material 2- attachetl to the back board 3, and the frontboard 1, all in accordance with the usual bellows construction. The back board 3 carries at its bottom the casting 5 comprising a rectangularshaped cup portion 6, the bottoinof which is extended to form the base 7. The bellows 1 is suitably connected to the cup 6 to form an air-tight joint therewith. The base 7 f the casting 5 is provided on its under side with a circular flange 8 of a size to receive the metallic screw cap 9 of the usual and well known fruit jar 10. The

Jitioned at the top central portion of the back plate 3, which serves to support the upper portion of the stirring rod 45, Figs. 1 and 3. This stirring rod passes. through the coinpressible material 2 of the bellows and extends downwardly within said bellows and through the passage 15 in the bottom of the cup 6, into the'jar 10,.wl1ich is adaptedto contain the powder-like material 50 to be applied to the plants, lVithin the jar 10, the stirring rod 45 is bent to form aU- cap 9 is secured in any suitable way to the loop 5.1constituting an agitator in order to base 7, asbytherivets l1. Tliebase 7 and facilitatethe stirringof the material 51). the top of i;l 1 e. cap 9- are provided With the Thus it will be seen. that the agitator 511s adapted to oscillate, through the powder 50, using as a pivot the stirring rod 45 which extends through the bellows 2 as a pivot. The link and the turned-over end portion 43 of the stirring rod are so formed and dimensioned as to be in all instances angularly-disposed one to the other.

The flexible hose 20 is bent around. and downwardly as clearly shown in Figs. 1

and 2, being held in this position by a hook carried by the end 36 of the base 7, of the casting The end 56 of the hoseQOmay be provided with any suitable sprayingnoszle s ch as 57, to suitthe needs of the device.

From the foregoing, it will now beseen that the operation of the device is as follow":--Powdered material having been placed in the container 10 and the latter having been screwed intooperative position on its cap 9 rigidly attached to the base 7, the operator will take the device tothe plants to be sprayed. As clearly shown in Fig. 1, the handle 26 is grasped by the hand, as shown, and the operator then walks down the rowof plants to be sprayed. The device will assume a position slightly angular f to the perpendicular, and as best illustrated in Fig. 1 in full lines. \Vhen a plant is reached upon which the powder is wished to be sprayed, the operator, by a wrist movement, gives a slight kick or throw forward to the device. This action will, due to the weight of the mechanism, cause the container 10 and its attached parts to swing forward, revolving about the pin as a center, but the handle 26 being still retained by the operator, the bar 30 carried thereby and pivoted thereto, will swing upwardly about pin 61 as a center, and as clearly shown by the dotted lines in Fig, 4. The result of this action, of course, will be to compress the bellows 1, forcing the air contained therein through the passage 15 in the bottom of the cup 6, into the or container 10. passage 15 being relatively smaller than the passage 16, the air will be directed in a blast against the powdered material 50, and, in escaping through the tube 20, will carry along with it some of the powdered material, r I The kick or throw imparted by the operator is very quick or instantaneous in action, with the result that the weight of the device will return the same to its normal or full line position, as shown in Fig. 4t. When the next plant to be treated is reached, the operator repeats his wrist action, thereby giving the device another throw forward, whereupon the bellows will operate as described above and the powdered material 50 will be delivered from the nozzle 57 under the plant. The action imparted to the device by the operator through the wrist movement is very easy. with the result that asthe operator walks down arow of young plants This tion. Upon full expansion of the bellows 1,

the link 40 will be moved away from the back boart 3,.and in so doing, will turn the agitator 51 located in the powdered material 50to such a position as indicated at (35. On the other hand, when the bellows is compressed, the link all) will force the extension 43 of the stirring rod in a direction indicated by the arrow to such a position as indicated at 66, whereupon the agitator 51 will move to such a position as indicated in dotted lines at 67. Thus, it will be seen that the material 50 is agitated within the container 10 upon each operation of the mechanism automatically.

The spring 35, it will be noticed, in Fig. 4-, is placed under tension each time the bellows is compressedi Therefore, the spring operates to aid the opening or return of the bellows to its fullor normal position.

The advantages of the device will be ob vious but may be briefly summarized as follows. Powder Sprayers have generally been so designed that upon applying the powder therefrom said powder will be diffused not only upon a portion, of the plant but upon the field as well, and the percentage of powder left on the field as in many instances has been far in excess of that placed upon the plant. This device is small, light in weight, simple in construction, and cheaply manufactured. It is portable and because of its size may be easily carried between the rows of plants to be sprayed.

The control of the powder/whereby the same is directed from the noZzleimmediately upon the plant isa valuable-feature. The nozzle which may be of any height may be so positioned as to apply the powder on the upper as well as on the under side of the leaves of the plant.

A still further advantage is in the container 10 which in this instance has been shown as a' well-knowntype ofglass fruit jar. Most every farmers wife has on hand a quantity of such jars and in case of breakage the replacement of the broken part may be easily made. By using such a jar the contents of the same are always visible and no parts. have to beidisengaged one from the other to ascertain whether said container needs replenishing.

It is obvious that those skilled in the art may vary the details of constructior; as well as arrangement of parts without departing from the spirit of the invention and therefore it is not desired to be limited to the construction shown except as may be required by the claims,
